audio quality variation of violin

So I have musescore downloaded on 2 computers. On one computer the audio of the violins are are incredibly good and sounds just lie the real violin maybe even better I may say. However on my other computer the audio quality of the violins are the kind of robotic old sound of the violin. I've checked the version of both and they are the same. What is happening?
